so much RMT!

I have trouble believing that. Most likely they just confiscate the Gil. If SE banned as many people as they say they have server populations would be a lot smaller then they are. I am sure that they ban the sellers and spammers but with the free trials and the like it is not hard for the RMT to return

It's hard to notice when a RMT spammer gets banned because they were never part of the operating playerbase in the first place. They were level 1 somewhere spamming tells and friend invites.

And Free trial accounts can't send tells.

I looked at a couple sites for the lulz (on my tablet, of course! I trust them about as far as I can ban them, not at all.). There's one thing that I found interesting between some of them.

They seem to have a thing with the Ul'dah mail moogle. They said that they would meet face-to-face there, so I don't think it's a far stretch to assume that's where they mail it out at either.

Put some form of a tracker on that mail moogle, as well as the ones in the other cities in case they catch on (yeah, they might actually move into the wilderness, but we're talking baby steps here). If it's noticed a level 1 character is sending out a lot of gil, you should be able to track both a buyer and a seller.
